If the set A has 3 elements and the set `B = {3, 4, 5}`, then find the number of elements in `(A xxB)`.

Explanation

To find the number of elements in the Cartesian product \( A \times B \), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Sets**:
- Let set \( A \) have 3 elements. We can denote these elements as \( A = \{ a_1, a_2, a_3 \} \).
- Set \( B \) is given as \( B = \{ 3, 4, 5 \} \).
